' To @ZZ whom it may concern:

Be it known that I, EDMUND H. LUNxEN, a citizenof the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain newand useful Improvements in Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, formingpart of .this specification. v

. My invention relates to windows for buildings which have sliding sashes to be raised and lowered, such sashes consisting usually of the glass-carrying sashes, blind or shutter sashes, and outside screen-sashes; l and it has such windows, whereby their weather and dust proof qualities are increased, the efficiency of all of the working parts secured, combined with lightness, compac tness, and durability, provision made for the raising of the sashes or any of them into a box or casing above and forming a continuation of the window-frame, as welll as provision for having the blinds or shutters upon the inner side of the glass-carrying sashes or upon the outer side of the same, and also provision made for swinging the main glass-carryin g sash bodily from its upper edge into the roomA to permit the outer sideof the glass to be washed.

It also has for its object thevarious constructions and combinations of the parts, all

as will be hereinafter more fully set forth,

and specifically pointed out in the claims.

In the accompanying drawings, Figure 1, Sheet 1, is an inside elevation, partly in section, of a Window embodying my present invention under one form of construction. Fig. 2, Sheet 1, is a sectional side elevation on the dotted line a: of Fig. 1 looking tothe left. Fig. 3, Sheet 2, is a view corresponding to Fig. 1 of my improved window under another form of construction. Fig. 4, Sheet 2, is a sectional side elevation on the dotted line y y of Fig. 3 looking to the left. Fig. 5, Sheet 3, is an enlarged broken view corresponding to Fig. 2 to show the parts more plainly. Fig. 6, Sheet 3,- is a similar view to Fig. 5, except that the glass-carrying sashes are of the ordinary standard construction and no provision is made for sliding them into a box or casing above the window-frame. Fig. 7, Sheet 3, is

vconstituting the weightl will iirst describe my improved window under the constructions illustrated in Figs.' 1', 2, 5, 10,'11`, and 12in connection with the detail views to be referred to in the' description. f

. In the iigures above referred to the frame surrounding the window-opening is composed of a metal pulley-stile 1 on each side, behind which is secured by screws or rivets a metalV box or casing 2, Figs. 1, 10, and 16, with division-walls 3 to form the various weightwells, a head 4, stool or sill 5, and pilasterfacings 6 on each side. Theouter-wall of the building 7 abutsragainst the. outer side of the weight-box and the inner side of the pulleystile 1, as seen in Fig. 10, and also across the ICO floor-supports 10 into the room above. The weight-boxes, however, do not extend higher than the head 4 of the window-opening, as seen in Fig. 1.

The guides for the various sashes are all contained in the inner sid es ofthe pulley-stile, and in the construction of the figures inentioned (see Figs. lO and 11) 11 is the upper glass-carrying sash, sliding between partingstrips 12 and 13, contained in recesses in the pulley-stile 1. The lower and main glasscarrying sash 14 slides between the partingstrip 1 3 and an interior slidable T-shaped strip 15, contained in a correspondinglyshaped groove 16 in the pulley-stile 1. One of the pulleys for the lower sash 14 is shown at 17, Figs. 1 and l0, and 18 is its weight and 19 its cord or chain, these parts being of the usual or any suitable construction. The weight 2O for the upper sash, as seen by the dotted lines, Fig. 1, is at the lower part of the well-box when said sash is raised and closed, and its pulley 21 is in line with the pulley 17,. seen in Figs. 2 and 5, the upper sash when closed has its top rail in close contact with the lower edge of adivision-piece 22, standing vertically in the boxor casing 9, which division-piece divides said box or casin g into two compartments and serves in connection with the upper rail of the upper sash to exclude all air and dust when the sashes are closed. In addition to being guided by the partingstrips 13 and the T-shaped guide-strips 15, which latter are just about the length of the side rails of the lower frame or somewhat less, the exterior edges of the side rails of the lower sash are grooved, as seen at 23 in Figs. 10 and 11, so that when said sash is raised within the box 9 said grooves engage tongues or guides 5U, confined in grooves in the pulley-stile 1 and projecting therefrom, as shown in Fig. 11. The parting-strips 13, however, continue unbroken to the top of the box or casing 9. lVhen the two sashes are closed, their meeting-rails 24 and 25 are locked by any suitable sash-fastener. I have, however, shown a preferred forni of sash-fastener in Fig. 7, where a spring-projected bolt 26 is contained in a bore in the rail 24 and has its projecting end engaging a socket in the rail 25. The interior projecting end of the bolt 2G is connected to a bellcrank lever 27, bearing aga-inst the rail 24 and provided with an operating pull-cord 2S, by which the bolt can be retracted to unlock the sashes, as will be readily understood. This feature, however, forms no part of my present invention, as any other suitable side locks or meeting-rail locks might be employed for the two sashes referred to.

Pivoted to the under side of the upper sash 1,1, preferably at its middle, is a pendent rod 29, (see Figs. 1, 2, and 12,) which in this insta-nce is shown as serpentine in shape, though it is rigid and the shape given it is more for ornainentthan anything else. This rod serves the double purpose of affording a means to pull down the upper sash when the lower sash is raised and also to engage with the lower rail of the lower sash when the latteris swung inward for the purpose of cleaning the outer side of the glass, as seen in Fig. 12. To thus draw inwardthe lower sash without detaching it from the frame, it is only necessary to slide up the strips 15, which are provided with linger-hooks 30Fig. 15,forease of manipulation and whose lower ends are notched or grooved, as shown at 31, and then to raise the lower sash sufficiently for it to clear the shoulder 32, Fig. 12, at its bottom, whereupon the sash can be drawn bodily inward at an incline, with the cords 19 engaging the notches 31 in the lower ends of the strip 15 and also notches 33, Fig. 13, in the grooves 23 at the upper edges of the sash, thus forming a Iiexible hinge for the upper edge of the sash without the necessity of pivot-bolts to enable the sash to be drawn bodily inward at an incline, as seen in Fig. 12, and then the rod 29 is made to engage at its free end with any suitable aperture 34 in the lower rail of the sash. To replace the sash in its frame, it is only necessary to disconnect the rod 29 and then partially raise the upper sash 11, so as to get the rod 29 out of the way, whereupon the sash 14 may be pushed back against the parting-strips 13 and the slides 1 5 be lowered to the bottom of their grooves, whereupon the two sashes are again in operative position for being raised and lowered inthe ordinary manner.

I will now describe the shutters or blinds which in the 'figures above referred to are just outside of the glass-carrying sashes. Two of these shutters are represented, an upper one 35, which is the exterior one, and an inner lowerone 3G. (See Figs. 5 and 1l.) The sashes of these shutters are connected by cords 37, (see Fig. 9,) secured to the lower edges of the sashes and passing over pulleys 38, Fig. (i, in the pulley-Stiles 1, and with their lower ends attached to weights 2O in their appropriate compartments in the weight box or well 2. It is preferred that the weights for these shutters should overbalance the same, so that where they are pulled down and then released the weights will automatically draw them up within the box or casing 9, as seen in Figs. 2 and 5. The side rails ofthe shutter-frames are grooved to receive tongues 39, Figs. 9 and 11, which are fastened therein by screws or other means 40 and which are conti ned in grooves 41 in the pulley -stile 1, said grooves extending the entire length of the window-frame and inclosing box or easing 9. As seen in Fig. 11, there is room in said grooves behind the tongues 39 for the free passage oi' the weight-cords.

A lug or plate 42, secured to the top rail of the outer shutter-sash, extends over and engages the top rail of the inner shutter-sash when both are raised within the box 9, as seen in Fig. 5, and the lower rail of the outer shutter-frame is provided with pendent rods 43, one at each side and having hooks 44 at their lower ends. lVhen it is desired to close the IIO shutters, it is only necessary to drawdown .the rods 43vand engage Vthe hooks 44 in recesses 45, Figs. 5, 6, and 10, which recessesare partially covered by locking plates 46, whereupon both shutters willlie side by side and will cover the upper half of the windowopening. yThe inner lower shutter may then be drawn down'by hand and may be locked at any desired 'point by side bolts on its frame and when entirely closed by a spring-projected bolt 47, Fig. 2, beneath the sill 5 with a pull-button within the room and a projecting latch-piece under the sill, which engages with a perforated lug on the under side ofthe A shutter-framewhen the latteris entirelydown.

As seen in Fig. 6, itis to be noted that'when the lower shutter is entirely closed it thereby locks the hooked lower ends of the rods 43 in their recesses, so that the upper shutter can-l ing 9, as seen in Figs. 2 and 5, to remain dur.

ing the winter or at such times whenit is desirable to entirely uncover the window-opening. I consider this `feature ofthe provision of aboxor casing above the window-opening for the screens as an essential featureof my frames, I have shown the shutter-frames as located inside of the glass-carrying frame, as

-this arrangementof parts maybe preferred by some persons. The construction of all the operating parts remains the same except the change in location and .except that I have dispensed with the overhanging4 lug or plate 42.V Hence I have preserved the same numer-v als of reference to designate the parts.. In addition I have providedY a notched bar 52',

. which ispivoted at its upper endv to the top rail of the outer shutter and passes through.' a `staple 53 on the toprail .of the inner shut-A ter. The shutters can both be overbalanced," as before, andthe lower inner shutter may have a side lock 54 or a'chain 55, engaging a pin on the sill 5, for holding the inner lower shutter locked, either completely ydown or atY By thev manipulation ofany point desired.

the bar 52V and the engagement of any one of its notches with the staple 53 the :relative positions of the shutterswith respectv to each extent desired vto uncover the upper .part of i the window-opening, as will be readily understood. y

While I have illustrated 1 and. described weights as the means for balancing or overf balancing the various sashes, it is apparent that spring-balances, such as are sometimes used in window construction', might be substituted for the weights. l A

As a simple and efficient means for holding the mainlower sash between its guide-strips 13 and 15 (see Fig. 8)iagainst rattling and to exclude airand dust, I provide a springmetal weather f strip 5S, made of spring. sheet metal doubledv upon itself, with Yits doubled portion secured in a kerf or groove in the strip 13 and with its divergent ends bearing between the inner side of the strip 13 and the outer side of the sash -14 on each side ofsaid sash, as clearly indicated in Fig. 8. Again, while I have shown but a single rod 29 secured to the middle of thelower.

rail of the upper sash l1,- if desired two of such rods may be employed, the one being secured at one side of the sash and the other at the opposite side of the sash, both serving to raise and lower the sash and serving as props for the lower sash 14 when swungin# ward to the position shown in Fig. 12. Y

By reference tovFigs. 10 and 16 themanner of securingthe metal 'division-walls 3 within the weight-box 2 is clearly indicated. The inner edges of said division-walloccupy grooves in thev pulleystiles,and their outer edges'are held in place bytongues 57, Fig. 16, punched from .the outer walls of the sheet-metal box 2, which tongues are bent inward alternately on opposite sides of the outer edges of the division-walls to hold the same securelyin their properly-adj usted positions, as will be readily understood. Y

Subj ect-matter shown and described in this application but not claimed forms part of the subject-matter of my prior application filed- November 24,.1902, Serial No. 132,616, and-is claimed therein. Having thus fully described my invention, I claim- A f 1. In window construction, the combination or" a frame, a glass carrying sash slidable ico IIO therein, means for balancing said sash, an in-` v 1` terior guide-strip for said sash slidable in said interior guide-strip for said sash slidable in said frame and adapted to be raised above the same topermit the latter to be swung bodily -frame and adapted ,to be raisedv .abovethe' l 3.
